Abstract
Wireless power transmission has been studied extensively for many years and has mainly been developed at 2.45 GHz, 5.8 GHz and 30 GHz. In the wireless power transmission system, the incident microwave power is converted into DC power by the rectifying circuitry, which is basically a high efficiency detector. The power conversion efficiency that is defined as the ratio of the DC output power to incident microwave power is key parameter to specify the system.

In this paper, a rectifying circuitry that efficiently converts L-band microwave power into useful DC power is suggested. The circuitry consists of two Schottky diodes, HSMS8202, and two capacitors. Simulative experiment observed output voltage with AppCAD, a RF device simulator. A impedance matching circuit for transmitting a received microwave power into the rectifying circuitry is designed by using the ADS simulation tool. To measure the conversion efficiency of the fabricated rectifying circuitry, the microwave power up to 14dBm is supplied to the rectifying circuitry by a signal generator. The fabricated rectifying circuitry acquired about 70% conversion efficiency at 1.65 GHz when input microwave power is 10dBm and a load resistance is 2.2 kΩ.
